HYDRAULIC MOTOR.

SPECIFICATION forming part of Letters Patent vNo. 298,102, dated May 6, 1884.

Application tiled November 14,1883. (No model.)

.T all whom it may concern,.-

Be it known that I, ROBERT LEUOHsENRING,

a citizen of the United States, residing at New Bedford, in the county of Bristol and State of Massachusetts, have invented a new and useful Water-Motor, of which the following, in

connection with the annexed drawings and letters-'of reference thereon, is a specication.

My invention consists in an impact waterwheel wherein is provided a novel adjustable and removable supplying contrivance, a novel indicator, a novel guarded air-vent, and a series of separately-constructed buckets'l applied upon a rabbeted hub, whereby the speed of the wheel can be regulated and indicated I to an almost innitesimal degree by hand or a speed-governor, the stream of water applied in a broad film-like sheet across the whole width ofthe buckets, the wheel supplied with air, and an undue accumulation of water in the outer or surrounding case of the wheel, and annoyance from suchwater escaping at the air-vent, and also retardation of the wheel by reason of the rotation of the exhaust water therewith prevented, while facilities for repair of the wheel proper and of the regulating contrivance are afforded. In the accompanying drawings, Figure 1 is a vertical central section through the wheel, buckets, and adjustable supply contrivanceof my invention. Fig. 2 is a vertical transverse section of the same in the line a: :c of Fig. 1, showing also the improved air-vent. Fig. 3 is a detail front view of the adjustable supply apparatus. Fig. 4 is a perspective top view of two contiguous buckets. Fig. 5 is a perspectivebottom view of one of the buckets constructed in conformity with my invention. Fig. 6 is an elevation and sectional view showing a power-governorsubstituted for the handregulating screw of the supplying contrivance.

A represents a. case; B, an impact waterwheel; C, an adjustable conduit; D, an airsupplying vent; and d, a semcylindrical tube applied over the said vent and extended up nearly to the highest part of the case.

The case A may be of any suitable shape, preferablyin form of a scroll, as shown. In

the projecting portion A a large rectangular 5o inlet, c, is provided, and in its divergent or elongated curved portion AZ-the outlet a is formed, while at-the center of its concentric portion A bearing-hubs a2 a2 for a shaft, b, of the wheel B, are constructed.

The wheel proper, B, consists of a hub, b', 55 arms b2, periphery b3, provided at either side with a rabbet or step, b4, and a number of buckets, E. Each bucket E consists of two side portions, e, a face-plate, e, and a bottom bolting-ilange, e2, with a screwl1ole,e3, in it. 6o The face-plate e and bolting-tlange e2 of the bucket are held upon the middle or higher portion of the periphery b3 by means of ascrew, c, and the side portions, e, rest upon the rabbeted edges or steps b, to which they are Y snugly fitted. The ends e5 of the side portions, e,.of the bucket are shaped -to make a perfect fit with the faceplate cof an adjoining bucket, and thus when all the buckets are set in place they form two continuous circular side rims 7o for the periphery ofthe wheel, as well as a number of water-tight compartments of equal area, and open only at the louter periphery of the wheel proper. j

An undue accumulation of eXh aust-water inside of the case A and about the wheel B is prevented by the vent-hole D in the case A, and saidV hole, being covered by the vertical gutter-shaped air conductor or pipe d,is adapted for freely admitting air into the case,while 8O lat the same time splashing of water through the hole-D and outside of the caseAis avoided. The water is let into the case A and upon the wheel B by means of the adjustable conduit or inlet device C, which is constructed with a rectangular chamber, c, having a suitable head, c', (into which in practice the supply-pipewill be screwed,) and one or two flanges, c2, which, by means of set-screws c3, are fastened to the outer face of the projection A', containing the 9o opening a of the case.

p Below the head c an inclined water regulating or supply guide, c4, made yielding at o9, is fastened by means of a screw-bolt, c5, to one of the inner end walls of the conduit C. This guide is fitted to move water-tight between the movable plates 010 of the conduit, which plates are secured by screws cl2, and it can be readily removed from the conduit for repairs or renewal after the same has been unscrewed roo at c and taken out of the inlet a by unscrewing the plates el and turning back the bolt cf. A spring, F, held in place also by the bolt c5, bears against the guide c* and acts to hold or force the guide away from the inner or righthand side of the conduit C. A set-screw, f, passed loosely through the lower portion of the outer wall of the projection A, and screwed into the left-hand side of the conduit C, bears against a straight surface, c, of the guide c", and by turning the screw f to the right the water-supply-regulating guide c* is caused to approach the inner or right-hand side of the conduit C, and by turning the screw in a reverse direction the guide c", by force of spring F, recedes from it, thereby either diminishing or enlarging the rectangular supply-orifice eT of the conduit, and thus regulating in the most etlective manner, and to the nicest degree, the quantity of water for operating the wheel B, such water being supplied iu a broad nlm-like sheet across the whole width of the buckets of the wheel. The screw f extends through the outer wall of the inlet, opening a of the projection A of case A, and is there provided with a fiat head, ,f, and pointer A graduated dial, F, is attached to the case A opposite the pointer f2, and by this means the speed of the wheel is indicated, and the operator is enabled after a little experience to at once set the screw f in the right position, in order to admit the proper or desired quantity of water into the wheel B for any required amount of power.

Instead of the screw f, worked by hand, as an adjusting and governing means, a powergovernor may be employed, as shown in Fig. 6,' whenever most desirable. The governor L, shown in said figure, is suitably fastened to the projection A of case A, and its sliding stem l passes through the projection A into the conduit C, and rests in a spindle-bearing, l', fastened in the side o of the waterregulating guide c, and its collar Z2, to which the balls l are fastened, is, by means of a pulley, Z,and the usual bevel-gears,revolved from the main shaft b,whieh is provided with a pulley, Zf, and belt Z5, and as the velocity of the wheel B increases this sliding stem Z will be moved, and with it the guide et, and thereby is diminished the size of the supply-passage c7, and while the velocity of the wheel is being restored through these means to the proper or set speed the spring F acts to move the regulating-guide back to its proper or original set position.

rIhe water-wheel herein described may be set so as to have the conduit C either vertical or horizontal, or in any other desired position, and so also may its discharging end stand either to the right or left.

The within-described conduit C, provided with the adjustable water-supply -regulating device, may be used advantageously in connection with other water-distributers and for various purposes.

V hat I claim as my invention, and desire to secure by Letters Patent, is-

l. The combination, with the water-wheel and its inclosing case having a broad rectangular inlet, a, ot' the conduit C, closed on all sides, and provided with ailexible water-supply-regulating guide, et, having a broad surface, and a governingv means, substantially as and for the purpose described.

2. The combination, with the water-wheel and its inclosing-case having a broad rectangular inlet, a, ofthe conduit C,closed on allsides, and provided with a rectangular chamber, and a iexible water-supply-regulating guide, et, having a broad face, the adjusting serewf, pointer fl, and dia-l F', substantially as and for the purpose described.

3. The combination, with the water-wheel and its inelosing-case,of the conduit C, closed on all sides, and having the broad surfaced adjustable guide o,which is made iiexible at c", and provided with a spring, and adapted to be fastened within the rectangular chamber of the conduit by a screw-bolt, substantially as and for the purpose described.

4. The removable conduit C, provided with a coupling-head, c', a rectangular chamber, c, bolting-fianges c, screw-plates c, and a ilexible removable water-supply-regulating guide, c, fitted within the chamber, in combination with the projection A@ substantially as and for the purpose described.

5. The combination of the wheel B and the water-motor case A A A2, having a suitable conduit, C, and the air-supplying vent-hole D, covered by the tube d, substantially as and for the purpose described.

6. In a water-motor, the wheel B, havingits periphery formed with circular rabbets bt, and its buckets E,const1ucted separately with their face-plates e and side portions, c, fitted to the rabbetcd periphery, all substantially as described.

7. In a water-motor, the wheel B, having separately constructed buckets E, provided with face-plate c', side portions, c, flanged bolting portions e, and end portions, es, fitting the face-plate c, substantially as described.
